Special For Oil Field Globe Valve

The high quality special for oil field globe valve produced by JQF Valve factory, is a forced-seal valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to prevent leakage at the sealing surface. When the medium enters the valve from below the valve disc, the operating force needs to overcome the resistance, including the friction between the valve stem and the packing, as well as the thrust generated by the medium pressure. The valve disc diameter should be large enough; otherwise, the valve stem may bend and fail.

1. The special for oil field globe valve meets advanced domestic and international standards, is easy to stamp, has excellent performance, and an attractive appearance.
2. The damper plate and valve seat packing surface are vertically aligned (stellite) with iron-based alloy overlay or partially with cobalt-based hard overlay, resulting in excellent wear resistance, heat resistance, anti-corrosion properties, and long service life.
3. The special for oil field globe valve adopts a wedge-shaped flexible gate structure, with bearings installed in medium and large diameters, ensuring flexible opening and closing.
4. The valve stem is quenched and nitrogen-treated, providing excellent resistance to erosion, scratches, and wear.
5. The special for oil field globe valve can be used with various standard pipe flanges and flange sealing surface types to meet diverse project needs and user requirements.
6. Valve body materials, types, packing, and gaskets can be rationally selected according to actual working conditions or user requirements, making it suitable for various pressure, temperature, and media conditions.

Installation Requirements

1. Thorough Cleaning: Remove impurities from the internal cavity of the oilfield valve before installation and repair any damage caused during transportation.
2. Proper Lubrication: Fill all moving parts of the transmission mechanism with lubricating oil before commissioning.
3. Angle Correction: Ensure the valve shaft is horizontal (butterfly valve) or the valve core is vertically upward (piston valve) during installation.
4. Transmission Pre-Inspection: Test the transmission function before using the special for oil field globe valve to ensure reliable stroke limit and overload protection.
5. Thorough Reading of the Manual: Carefully read the electric actuator operation manual before powering on.

Product parts materials

1. Regular Inspection: After using the special oil field globe valve, its opening and closing status should be checked regularly, and any problems should be addressed promptly.
2. Frequent Lubrication: Regularly add lubricating oil to the moving joints to maintain smooth rotation.
3. Timely Replacement: If the piston is found to be not closing tightly, the rubber ring gasket should be checked and replaced.
